Spammy Subject Lines Exposed: Safeguard Your Email Reputation Now

Email filters flag certain words as spam as part of their efforts to protect users from unwanted or potentially harmful content. These filters are designed to recognize common characteristics of spam emails, including certain words and phrases often used in spam messages.

Words associated with deceptive or overly aggressive marketing tactics are often flagged as spam. Similarly, subject lines that use excessive capitalization, punctuation, or clickbait tactics can also trigger spam filters.

This is important because if an email is flagged as spam, it’s less likely to reach its intended recipient, as it may be automatically moved to the spam folder or blocked entirely. This can significantly reduce the effectiveness of your email marketing efforts.

Consistently having your emails marked as spam can harm your sender reputation, making it even more difficult for your future emails to reach inboxes. Understanding which words and tactics to avoid in your email subject lines can help improve your email deliverability and the overall success of your email marketing campaigns.

Why Would An Email Subject Line Be Flagged As Spam?

An email subject line can be flagged as spam for a variety of reasons, many of which are related to the use of certain words or phrases, the style of writing, and the overall approach to crafting the subject line.

Spam Triggering Words

Spam triggering words are certain words and phrases that flag spam filters. When these words are used in an email subject line, they can trigger spam filters, causing the email to be flagged as spam and potentially preventing it from reaching the intended recipient’s inbox. Here’s why:

  • Association with Spam: Spam trigger words are often associated with spam emails. These words and phrases are frequently used in spam messages, so spam filters are designed to recognize and flag emails that contain them.

  • Aggressive Marketing Tactics: Many spam trigger words are associated with aggressive or deceptive marketing tactics. For example, phrases like “Earn $$$”, “100% Free”, “Get it now”, and “Limited time offer” are often used in spam emails to try to entice recipients to open the email or take a certain action. Using these phrases in your email subject lines can make your emails appear spammy and can trigger spam filters.

  • Misleading Promises: Some spam trigger words and phrases make misleading promises or create unrealistic expectations. For example, phrases like “Once in a lifetime”, “No cost”, and “No obligation” can create a sense of urgency or suggest that the recipient is getting a deal that’s too good to be true. These types of promises are often associated with spam emails, so using them in your subject lines can trigger spam filters.

  • Impact on Sender Reputation: Using spam trigger words in your email subject lines can harm your sender reputation. If your emails are frequently flagged as spam, it can make it more difficult for your future emails to reach the inboxes of your recipients. This can reduce the effectiveness of your email marketing efforts and can harm your relationship with your recipients.

Misleading Language

Subject lines that are vague, misleading, or exaggerated can confuse or frustrate readers, leading to your email being filtered as spam. It’s better to use clear and concise language that communicates the value and relevance of your email.

  • Misleading Impressions: Misleading language in subject lines can give recipients the wrong impression about the content of the email. If the content doesn’t match the subject line, recipients may feel deceived and mark the email as spam.

  • Triggering Spam Filters: Email spam filters are designed to protect users from spam and phishing attempts, many of which use misleading language in their subject lines. Therefore, using misleading language can trigger these filters, causing your email to be sent to the spam folder or blocked entirely.

  • Damaging Sender Reputation: If recipients frequently mark your emails as spam due to misleading subject lines, it can damage your sender reputation. This can make it more difficult for your future emails to reach the inboxes of recipients, reducing the effectiveness of your email marketing efforts.

  • Reducing Engagement: Misleading subject lines can reduce the engagement rates of your emails. If recipients feel that they can’t trust the subject lines of your emails, they may be less likely to open them, reducing your open rates and overall engagement.

To avoid these issues, it’s better to use clear and concise language that communicates the value and relevance of your email. This can help build trust with recipients, increase your open rates, and improve the overall success of your email marketing campaigns.

Excessive Use of Capitalization and Punctuation

Excessive use of capitalization and punctuation in an email subject line can make your email appear as spam, which can lead to it being filtered out by spam filters and not reaching the intended recipient’s inbox. Here’s why:

  • Perceived Aggression: Using all caps or excessive punctuation can come across as shouting or overly aggressive, which can be off-putting to recipients. It’s often perceived as unprofessional and can lead to recipients marking your email as spam.

  • Spam Filter Triggers: Spam filters often flag emails with excessive capitalization or punctuation as potential spam. This is because many spam emails use these tactics to try to grab attention. As a result, even if your email is legitimate, it could end up in the spam folder if you overuse capitalization or punctuation.

  • Affects Readability: Excessive capitalization and punctuation can make your subject line harder to read and understand. This can decrease the likelihood of your email being opened and read.

  • Can Seem Deceptive: Overuse of capitalization and punctuation can make your email subject line seem deceptive or misleading, as it can create a sense of urgency or importance that may not be reflected in the email’s content. This can lead to recipients marking your email as spam.

To avoid these issues, it’s best to use normal sentence case and minimal punctuation in your email subject lines. This can make your emails appear more professional and respectful, increasing the likelihood of them being opened and read. Additionally, it can help ensure your emails pass through spam filters and reach your intended recipients.

Remember, while it’s important to make your email subject lines stand out and grab attention, it’s equally important to do so in a way that respects your recipients and adheres to best practices for email communication.

Clickbait Tactics

Subject lines that use clickbait tactics, such as “Re:” at the beginning of the line to trick recipients into thinking there’s an existing conversation, can lead to your email being flagged as spam. It’s important to be honest and straightforward in your subject lines.

Unprofessionalism

Using emojis, typos, or unprofessional language in your subject line can make your email appear less credible and more likely to be marked as spam.

Remember, crafting an effective email subject line is about more than just avoiding spam filters. It’s about creating a clear, engaging, and relevant message that encourages your recipients to open your email and take action.

Compliance

The CAN-SPAM Act is a law that sets the rules for commercial email and establishes requirements for commercial messages. It gives recipients the right to have businesses stop emailing them and spells out tough penalties for violations. Use our CAN-SPAM Act compliance checklist to make sure your emails follow the regulations.

One of the key requirements of the CAN-SPAM Act is that subject lines of emails must not be deceptive. The subject line must accurately reflect the content of the message. This means that if an email advertises a product or service, the subject line should clarify this and not mislead the recipient about the email’s content.
